H110 in the .41 mag is tops with a 210 grain hornady xtp! Nothing on the planet can walk away from it. Load from 20 to 22 grains. I load 22 grains in Ruger .41 mag with this bullet and can consistently shoot 3.5 to 4" groups at 100 yd with scope on bags. 3" high at 50yds will be zeroed at 100...
Yes very good load, magentospeed at 3,190fps single digit es's. .5 moa accuracy. very temperature stable. Best load yet in the longer barrel. Good barrel time.

I don't load anything but H4350 in 300WSM with 150 - 165 grains bullets. Might get someone to QL the 150 Etip with H4350 and see what it predicts.
IMR4350 or 4451 will do too.
Personally I see both Varget and H4350 average about .3 fps per degree but have seen both actually be faster in the hot and the cold than mid range velocity at about 50-70 degrees in some caliber bullet combos. With IMR4064 it is more linear in that 20 degree speeds will be about 25-35fps slower...
IMR4064 is listed as most accurate in both Noslers manual and Barnes both with the 150gr monos.
Have temperature tested a lot of IMR4064 and is probably the most stable older IMR line there is, is just dang near as temperature stable as Varget and H4350. ( I usually see just under a .5 fps per...
Very Close! But H322 is much more temperature stable. I have seen 2015 be as much as 2.5fps per grain per degree, depending on caliber and bullet weight. 2015 seems to be a bit more stable with heavy class bullets, but still not in the class with H322.
H4350 is the most temperature stable powder I have tested in the 243 with 95 NBT. RL19 can have big swings in temps over 80 and under 25........
Best accuracy for me was at 2825fps in 20" barrel
2900fps in 22" barrel
SO 24" barrel should be bout 2980 +/-.
With 24" barrels the slower powders work great with the 95-100 grain bullets, but as barrels get shorter so does the need for faster burn rate powders, muzzle blast can equal that of a 7 Mag with the 20" and shorter barrels with the slow powder family........
24" barrels Imr7828ssc, RL26...
You did say really good.

4451 is dang near grain for grain with H4350 in the both the 243 and 30-06. Have shot it in both and equal speeds with 90 Scirroco in .243 @ 3,050 and 150 AB in 30-06 @ 2,988
I saw exactly the same thing in other calibers. What I found was that the RL 26 craves fire. Going to the Fed 215 primers and working load up again accuracy was much easier to find, FWIW.
Yes I ended up deer hunting the last half of the season with 90 Hunting BT. It performed on game very well overall. I am pleased enough with it to continue using if can't keep AB's in supply!
